Hiarcs 13 Professional Openings Book (PC-CD)

Ref: CPH13B

The Hiarcs 13 Pro book has a very large amount of playable variations which gives a lot of variety and means the book is able to address the needs of many different players, from human tournament preparation to online computer games. Despite having more variety than most other commercial books the Hiarcs 13 Pro Book is significantly stronger typically scoring 55+% in head to head matches between books with equal engines over 300 games. For example, in a match of 300 games against the highly rated Rybka 4 book, the Hiarcs 13 Pro book scored more than 55%. Hiarcs 13 customers who already have the Hiarcs 13 Lite opening book will be delighted to know the Pro book adds up to 50 Elo to the strength of the program. The book is written by Mark Uniacke, the author of HIARCS, and he has been supported by Correspondence IM Harvey Williamson and computer chess expert Eric Hallsworth, both of whom are also part of Team HIARCS. The HIARCS 13 Pro openings book can be used on it's own, with HIARCS 13 and your other favourite engines in any Chessbase graphical user interface.
